Does it plug in or does it only have battery power?

It plugs in and uses the battery for backup in the event of a power failure.

I'm sorry but the item is currently in my cabin in the mountains and has not been installed yet. I've had it for a while and don't remember. Sorry I couldn't be any help.

It plugs into an electric outlet and has a battery backup. My unit is in the north woods and I don't remember if the power line has a transformer on it or not

It plugs in. I can't remember if you can use batteries too, we just always use the plug.

Yes it uses batteries or you can plug it in (if you get all that come with it.) see the other reviews. I was apparently lucky to get both lol

Yes it works plugged in. I have never picked it up and found the battery dead. While using, if the battery needs charging, a red light comes on to indicate it needs charging. So when I am done using it, I plug it in. I have not yet had it die while using. Good battery life.

Only works when plugged in. There is a battery backup to keep the time during a power failure.

it plugs in, and recharges. I put them in 4 rooms and don't use unless power goes out.

I, frankly, don't remember exactly. But I have an impression that it's supposed to be plugged-in, no battery.

I don't know what you mean by plug in in this device.It is battery operated.

Yes. Plugs in or runs on battery. I've found the battery to last about 8 hours

Its not battery operated if that's what you are asking. You have to plug it in to use it.

No it's strictly plug in. If that's not a showstopper, then I would recommend it. I use it frequently!

No it doesn't need a plug in (Only batteries)...The product do have a port on the side if you are using rechargeable batteries, which is an option

No Judith, it plugs in. That was not really a problem for me though. The power is.

It has to be plugged into the computer using it's USB cord. That is also how it gets it's power.

It is not battery powered. It comes with a plugin transformer. Settings are retained in non-volatile memory, so if there is a power interruption, the settings remain intact.

It runs on batteries. You can plug in a 12V power source of your choosing. I use a universal power adapter that came with several plugs and found one that fits nicely.

It must be plugged in. But it does have a battery because there is a CAUTION: Risk of explosion if battery is replaced by an incorrect type.
